Mesterolone(CAT: R065159) is an orally active synthetic androgen and anabolic steroid (AAS) that is primarily used to treat male hypogonadism and infertility. It mimics the effects of testosterone, aiding in the development and maintenance of male secondary sexual characteristics. Unlike many other anabolic steroids, Mesterolone has a relatively low anabolic effect but a stronger androgenic effect, making it less likely to promote muscle growth but effective in boosting male libido and enhancing mood and energy. It is also resistant to aromatization, meaning it does not convert to estrogen, reducing the risk of estrogenic side effects like gynecomastia. Mesterolone is commonly researched for its role in treating androgen deficiency and related conditions.
